The gang decides to go to Ben's Chili Bowl, one of President Obama's favorite places in D.C. "It's one of our favorite places, to go," Jim Bob says. "We have that in common."

Kirk actually appeared on the show back when it was just 18 Kids and Counting. "We decided to get together tonight and have a little reunion," he explains.

But things soon take a turn for the awkward when a couple of fans want to take a picture. No, not with Kirk, but with Jim Bob and Michelle.

A fan hands the camera to Kirk so he can snap a picture, and afterward Jim Bob asks the fan if she'd like to take a picture with the Growing Pains star. "Do you know who he is?" he asks. "He's Kirk Cameron." Kirk just smiles and says nothing while the woman tries to explain why she didn't recognize him.
